8-bit Timer with External Trigger (TIMB)
The four possible operating modes are described in
Table 28
.
Note:1. The downcounter value cannot be read.
2. Change the EXT value to exit the External One-shot mode.
TIMER B CONTROL STATUS REGISTER (TIMCSRB)
Read/Write
Reset value: (00h)
Bits [7:6] = TB[1:0]
Time Base period selection
These bits are set and cleared by software.
00 Time base period = t
TIMER
(16 μs @ 8 MHz)
01 Time base period = t
TIMER
x 8 (128 μs @ 8 MHz)
10 Time base period = t
TIMER
x 16 (256 μs @ 8 MHz)
11 Reserved
Bit 5 = OVF
Timer Overflow Flag
This bit is set by hardware. An interrupt is generated if OVFE = 1. It must be cleared by reading the
TIMCSRB register.
0
No timer overflow
